it is easy in the theory but it is very hard to do,
a while ago when i was doing my first trade i thought that thing too,in the beginning everything is very smooth but when 'that' time comes,
it will rekt you down and in the end you will lose everything instead of gain anything from it.
indeed Bitcoin price can change while it get another news,something like listing,and similiar to that one.
but bear it in your mind,that Bitcoin price can be manipulated by people easily.
just like a week ago or two,without any news we could see a huge spike from $6000 to $7000,
in reality many people claimed that it would go down,so it's very risky to do the leverage when the market is volatile.
except you're the pumper or dumper themself,
other than them nobody can do something to the market.
I don't think this is true much, if not at all. If you really think about it, if you get some of the big tele groups/ wa groups/ twitter 'advisors' on board and they start spamming about a certain coin and how they're promoting people to buy it if they want to make some quick cash that'd be something that is going to create hype, not too hard if you're part of the elite owners of these coins before people start hyping them -- or before you pay massive amounts of people to HYPE these coins hard.
It's easy, you just have to know the right people to do it and spend some money to make some money.
